I have an F150 with the limited slip but this winter killed me without 4x4. You said you have a CJ so if it's not your daily driver it may not be a big deal but I'll never own a 4x2 again. I understand the advice that if its slippery, you don't belong out but that is not practical advice in New England, especially on a winter like this. If work doesn't shut down, you're driving on slick roads like it or not. I had to find alternate routes this winter because certain stop signs/lights on hills, I just couldn't get started even after adding weight to the bed of my truck.
